I remember reading this book 16 years ago and enjoying it immensely. I have just repeated that experience. I even remember some crucial clues, so much of the story was not surprising. However, I enjoyed the journey. I love how Mrs. Christie uses only a few words to describe her characters, yet we get a complete picture of their looks, fashion, and character. An example is the following: "She wore country tweeds - and with them, rather incongruously, a choker necklace of large false pearls." That's a pretty complete picture of Miss Blacklock.
